Original Ray-Ban RB4440N Blaze Wayfarer shield lens

If the shield lens on your Ray-Ban RB4440N is scratched, marked or no longer clear, you do not need to replace the whole frame. This original Ray-Ban replacement lens restores the look and sun protection of your Blaze Wayfarer at a much lower cost than buying new sunglasses, with free shipping included.

Model compatibility

This replacement part is made for Ray-Ban model 4440, also known as RB4440N Blaze Wayfarer. It is an original sun shield lens, not a pair of separate lenses like those used in classic Wayfarer models. The Blaze design uses a specific single-piece front lens with its own shape and fitting points.

Before ordering, check the inside of your temple arm. The reference should show RB4440, RB4440N or 4440. This is not a universal Ray-Ban lens and should not be fitted to other models, even if the front shape looks similar.

How to identify your model and size

Ray-Ban frames usually show the model, colour code and size on the inner temple. For this product, the available size is 41. That number must match your frame reference to ensure the shield sits correctly on the front.

If your temple reads RB4440N 41, this is the correct type of replacement lens. If your frame has two separate lenses or a different model number, this shield lens will not fit properly.

Material, protection and lens finishes

This shield lens is made from polycarbonate, a light and resistant material that suits the single-lens construction of the RB4440N. The Base 2 curve preserves the flatter geometry that defines the Blaze Wayfarer design.

The lens provides UV400 protection, blocking 100% of UVA and UVB rays. With a shield lens, correct geometry and optical quality are essential to avoid uncomfortable visual distortion.

Why replace only the lenses

Replacing the lens is the smart way to keep your original Ray-Ban frame, reduce waste and save up to 60% compared with buying new sunglasses. If the frame is still in good condition, a new shield lens can make it look and perform like your favourite pair again.

ReplacementLenses.net has repaired more than 600,000 glasses and handled over 400,000 orders in more than 50 countries since 2018. You can also browse our original Ray-Ban lenses.

Authenticity and logo

Because this is an original Ray-Ban product, original Ray-Ban lenses include the Ray-Ban logo. In our own workshop in Granada, qualified opticians check every lens with a lensmeter before dispatch.

We are an official EssilorLuxottica distributor, which gives you confidence that you are buying a genuine part rather than a generic copy with uncertain fit or optical quality.

Frequently asked questions

Will this fit classic Wayfarer sunglasses?

No. This shield is for the Ray-Ban RB4440N Blaze Wayfarer, not classic Wayfarer frames with two separate lenses. The RB4440N uses a single-piece shield with a specific fit.

What if my temple says RB4440 without the N?

Check that the model number is 4440 and that the size is 41. If both match, you are looking at the right replacement type for this product.

Is it an original Ray-Ban lens?

Yes. This is an original Ray-Ban replacement lens, and original Ray-Ban lenses include the Ray-Ban logo.

What material is the lens made from?

The lens is made from polycarbonate. It is light, resistant and appropriate for a square single-piece sun shield with Base 2 curvature.

Does it protect against UV rays?

Yes. It provides UV400 protection, blocking 100% of UVA and UVB rays for proper sun use.

Is there a polarised option?

No polarised variant is listed in the product attributes here. If you need polarisation, choose only a lens option clearly marked as polarised.

Can I install it myself?

You can if you have experience, but shield lenses require controlled pressure and correct alignment. If you are unsure, we recommend professional fitting by an optician.
